Hi,

What is the purpose of 'DFSRRC00', when and where one should use it? And there are so many parameters of it, what they stand for?

DFSRRC00 is known as IMS/universal region controller or IMS in Batch.

DFSRRC00 is controlled using a number of parameters.These Parameters differ depending from the execution environment (BMP, DBB, JMP, ...). The symbols in the JCL might be different at different sites, but the meaning remains the same.

Please have a look at the IMS Installation Guide Volume 2: System Definition and Tailoring. You can use the following link to get there - http://publib.boulder.ibm.com/infocente ... /index.jsp

Look for the procedure descriptions, e.g. IMSBATCH is the name for the BMP. Right after the sample JCL in section IMSBATCH Procedure Parameters is a list of all applicable DFSRRC00 symbols for this execution environment, for which the meaning can be looked up in section Parameter Description in the same book. All this applies to IMS V9 or earlier.

Thanks for the help Anuj. Do we have some document talking about individual parameters too?

Appreciate your help.

The reference documents from IBM are too complex at times and I'm not sure if I got it all well! :cry:
